sPHENIX tracking discussion

[Haiwang Yu <yuhw.pku AT gmail.com>]

Hi Christof, Tony and all,

I pulled in this change to my repository with some other changes.
https://github.com/HaiwangYu/coresoftware/tree/KalmanPatRec_merge_CR_2017_06_12

two libraries needs to be compiled:
simulation/g4simulation/g4eval
simulation/g4simulation/g4hough

To reconstruct primary/vertex tracks, simply turn on the set_fit_primary_tracks switch for PHG4TrackKalmanFitter like here:
https://github.com/HaiwangYu/macros/blob/KalmanPatRec_merge_CR_2017_06_12/macros/g4simulations/RunKalmanPatRec.C#L165

Another node containing the primary tracks will be created naming PrimaryTrackMap

And to use Christof’s evaluator to evaluate those tracks instead of the default SvtxTrackMap
One could change the SvtxEvaluator constructor like this:
https://github.com/HaiwangYu/macros/blob/KalmanPatRec_merge_CR_2017_06_12/macros/g4simulations/RunKalmanPatRec.C#L202

Cheers,
Haiwang

Hi, 

anybody who wants to geve the updated evaluator a try please look at:

https://github.com/bogui56/coresoftware/tree/master/simulation/g4simulation/g4eval

In this version all number of hits, layer and tru hit counts are filled for maps, intt and tpc.

Number of wrong (unmatched) hits are also counted now. 

There is an option to run the evaluator without truth matching, so one can just dump the 

entire event into the ntuple without the check for embed flag. To use this modify your 

macro like below:

SvtxEvaluator* eval = new SvtxEvaluator("SVTXEVALUATOR",

g4svtx_eval_out_name);

eval->do_cluster_eval(false);

eval->do_g4hit_eval(false);

eval->do_hit_eval(false);

eval->do_gpoint_eval(false);

eval->do_track_match(false);

eval->scan_for_embedded(false); 

eval->Verbosity(0);

se->registerSubsystem(eval);

Cheers
